China Announces Development of a New Ultra-Fast Optical Fiber That Could Revolutionize Various Segments. Capable of Reaching 125 TB/s in Data Transmission, Technology Will Be Crucial for Medicine.
Researchers from the Shanghai University of Science and Technology, in collaboration with Peking University and the Shanghai Institute of Optics and Fine Mechanics, developed a new optical storage technology that could revolutionize medicine and communications. The study, published in the scientific journal Nature, presents a high-capacity optical disk capable of storing up to 125 terabytes of data, using a three-dimensional architecture and nanotechnology to increase storage density by approximately 10,000 times compared to traditional Blu-ray discs. This innovation promises significant advances in the storage of large volumes of data, essential for medical and communication applications.
The Benefits of the New Ultra-Fast Optical Fiber
The main revolution of this data transmission technology lies in the integration of miniature diffractive neural networks, that is, microscopic structures the size of a grain of salt in multimode optical fibers.
This advancement addresses one of the greatest challenges of this material, the interference and distortion of light signals, which previously limited the capacity for data transmission.

The diffractive neural networks organize the light signals efficiently, reducing information loss and drastically increasing bandwidth. The method eliminates the need to convert light signals into electrical signals for processing, making data transmission more efficient and faster.
Out of curiosity, it is important to mention that optical fiber works on the principle of total internal reflection of light, which causes a continuous propagation of light inside with the least possible signal loss.
For this to be possible, it is necessary to launch a light beam into the core of the optical fiber at a critical angle (the limit angle for light not to exceed the other medium). It is also necessary that the refractive index of the fiber core be higher than the refractive index of the cladding that surrounds the core, so that light has multiple reflections within the core without passing through the cladding.
Scientists Test New Ultra-Fast Optical Fiber
Chinese scientists tested this new ultra-fast optical fiber in a 2,000 km connection between Shanghai University and a hospital in Hainan Island. The results showed significantly higher performance compared to current technologies, opening doors to new possibilities for data transmission in communication, medical image analysis, and quantum computing.
In addition to telecommunications, the new technology from China promises significant advancements in medicine. Scientists at Shanghai University of Science and Technology are already testing this new ultra-fast optical fiber to generate real-time brain images, allowing for unprecedented visualization of nerve cells.
This innovation enables the early identification of tiny tumors that would otherwise go unnoticed. Researchers are also exploring the use of harmless luminescent materials that can be ingested by patients, causing specific organs to emit light and facilitating the detection of anomalies.
New Technology Will Also Impact Quantum Computing
According to Yu Haoyi, associate professor at Shanghai University, it will be possible to identify pathological changes by integrating the device with a deep learning algorithm, improving screening and facilitating early detection, resulting in more effective treatment.
With such advanced speeds, this optical fiber has the potential to impact not only high-speed internet but also advancements in quantum computing. Its use could accelerate data processing to unprecedented levels, boosting sectors such as digital security, artificial intelligence, and big data analysis.
The discovery by researchers in China marks a crucial technological leap to redefine the future of data transmission and medicine. If this new ultra-fast optical fiber is widely implemented, the impact will be felt globally, resulting in faster internet, more effective medical examinations, and new possibilities for the computing of the future.
